Description of the invention (1) The present invention relates to a system capable of maintaining high flow in the system by the air blower impeller mm-heating, ventilation, and cooling; Γ, 'It still has a background of the invention even when the process medium is in a full plant state * For the air quality of 1 pound of "main thinking environment", I have come up with new and existing; r industrial gas circulation systems such as heating and ventilation and cooling systems for buildings and vehicles. hva: 1 ^ 2, Ventlatl 〇n, and cooling system, the following nr C = system) added transition capabilities. For example, most vehicles use HVAC systems that do not include air rolling filters. Usually I have a very small space for Li and ’_. In addition, it may be necessary to provide a first filter for air intake through a second filter for air recirculation in the passenger compartment. Even in new models, the space inside the HVAC system is still quite precious' and it is difficult to provide a suitable place for the filter to be used. In addition to the difficulty of finding sufficient space for filters, the effectiveness of most filter media has also raised concerns. After a period of time, environmental fouling = accumulation in the filter, which usually leads to passing through the air circulation system of the second parent = low. Inadequate regular replacement of the filter media will result in increased quietness through the filter ^ ^ and increase the efficiency of the air circulation system. Blocking the overheater $ ^ will also cause safety hazards, ... insufficient gas "for the HVAC system Defrost system. —Fang'an, National Patent No. 5, 68 3, 478 for the installation of an air filter on the vehicle's ΗVAC system. ^ 70665 of the air filter Five invention description (2) _______ ^, and the shape is made into the cavity located in the blower two on the base of the air filter with a stroke inside the motor assembly.

Description of the invention (22), the concentration of similar particles is reached in the center, but it is obvious from the data in Table 丨 that the "mobile filter type can be more cracked than the" static "filter. Quickly reduce the number of particles ° This performance difference is also reflected in the "mobile", "type" and "static" type of clean air transmission rate calculated by the "Cyclic" type (36.6 cubic meters / hour vs. 25 6 cubic meters / hour). Examples 2 to 4 In the following examples, the mobile filter according to the present invention was tested for its particle loading performance and its subsequent effect on air transfer.-Air inlet duct (about 15 cm in diameter, Length about 46 cm) is installed vertically above the additional filter device, and the air enters from the top of the duct & drains from the bottom to the center of the blower impeller. The inlet duct is placed in a TSI type, 837 ° "AccubalanceTM" Inside the hood of a flow measurement hood (produced by TSI, Inc., 5 5 1 6 4, Minnesota). The bottom of the flow measurement hood, 60 cm by 60 cm, is blocked by a piece of cardboard, and the 15 cm duct is passed through the cardboard. By ^ way ' Any air that enters the flow measurement hood will be exhausted through the 15 cm guide and mobile filter unit. The test dust is PFII fine powder (IS〇121⑽) from Powder Technology, Burnsford, 5533 7 , A2), which is distributed with an ASHRAE 52.1 dust feeder, as described in ASHRAE Announcement # 521_92, pages 6 to 8 (this dust feeder is A 丄 Γ, Guanmogi, KFC)

Filter Testing Laboratories). Dust feed rate was selected to produce a powder house location of approximately 75 mg per cubic meter at the mobile filter air inlet. The dust distributed by the dust feeder is sent to the throat of the 5 cm duct by compressed air through a 2 cm inner diameter " Ty gonTM " pipe. Filter pick

Description of the invention (23) 15 to 20 grams of fine test dust, which represents significantly more than the amount of dust that ordinary VAC systems will encounter during one year of normal operation. The fan operates at a voltage of 13 volts. Turn the impeller at about 2400 revolutions per minute 'or operate at 6.5 volts to rotate the impeller at about 1350 revolutions per minute (as indicated in the tables below). The filter core unit is composed of the aforementioned " F 1 TRETETMM GSB70 type medium, thereby creating an outer diameter of 19.4 cm., An inner diameter of 15.2 cm, and a height of 4.2 cm, which has 8 1 6 mm is the folded edge of the interval.
